2. Description of Related Art

A conventional stand for a display is shown in FIG. 1. A plurality of boards are individually formed by pressing and then be secured to each other to assemble the stand 1. As shown in FIG. 1, the stand 1 includes a main board 11, two side boards 12, and a top board 13. The main board 11 is formed with a plurality of screw holes 111. The side boards 12 and the top board 13 are formed with a plurality of holes 121 and 131. A plurality of screws 14 are capable of passing through the holes 121 and 131, and then be secured in the screw holes 111 so as to fasten the side boards 12 and the top board 13 to the main board 11. However, the conventional stand 1 has disadvantages of being structurally complex and bulky. Furthermore, the plates or boards should have certain thickness in the manner of fastening with the screws, which is unfavorable in the trend of having the slim stand.

In another aspect, the conventional stand is not possible to be integrally formed because a single and large mold for manufacturing a conventional stand is too expensive and lacks production efficiency.

Given the above, it is desirable to provide an improved display stand to have a slim structure with low manufacturing costs.

SUMMARY OF THE INVENTION

One objective of the present invention is to provide a display stand which has a slim structure and is capable of minimizing the unfavorable visual effect occupied by the stand from the view of the user.

Another objective of the present invention is to provide a metal extrusion plate for the display stand. The metal extrusion plate is capable of being bent as a supporting frame of the display stand. Merely a small mold can be used to manufacture the metal extrusion plate as a semi-finished product. The semi-finished metal extrusion plate can be further processed with grooving and bending to form the support frame. Thus, using the small molds can reduce the manufacturing cost and simplify the manufacturing processes.

To achieve the abovementioned objectives, the present invention discloses a metal extrusion plate for a display stand. The metal extrusion plate extending along a first direction and comprises N of flat plate sections and N−1 of connecting sections, wherein the flat plate sections are integrally formed with the connecting sections, N is a positive integer greater than 1. The flat plate sections are interlaced with the connecting sections, and each of the connecting sections is connected to the two adjacent flat plate sections therebetween. Each of the connecting sections has a groove extending along a second direction being perpendicular to the first direction and forming a first incline and a second incline opposite to the first incline. The metal extrusion plate is capable of being bent at the connecting section so that the two adjacent flat plate sections form a first included angle.

A side of the first block is connected to one of the two adjacent flat plate sections, a side of the second block is connected to the other one of the two adjacent flat plate sections, and two opposite sides of the third block are connected to the two adjacent flat plate sections respectively. The first block, the second block, and the third block collaboratively define the groove. The flat plate section has a first thickness greater than a second thickness of the third block.

The first incline is formed on the first block, and the second incline is formed on the second block. Before being bent at the connecting section, the first incline and the second incline form a second included angle in which value of the second included angle is complementary to value of the first included angle.

Preferably, in the metal extrusion plate of the present invention, the flat plate section that locates at either end of the metal extrusion plate is formed with a first engagement structure. The metal extrusion plate further comprises a first surface and a second surface opposite to the first surface, wherein the groove is formed on the first surface or the second surface. The material of the metal extrusion plate is aluminum or aluminum alloy.

In another embodiment, the present invention discloses a display stand comprising a base, a supporting frame being formed by bending the abovementioned metal extrusion plate for being disposed on the base, and an elevating module. The flat plate sections and the connecting sections of the supporting frame encompass and form a receiving space.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The present invention discloses a metal extrusion plate and a display stand. Please refer to FIG. 2 and FIG. 3, wherein FIG. 2 shows the schematic view illustrating the display stand 2000, and FIG. 3 shows the exploded view illustrating the display stand 2000. The display stand 2000 preferably includes a base 3, a supporting frame 5, an elevating module 7, and a supporting structure 8. One of the characteristics of the present invention is that the supporting frame 5 is formed by bending the metal extrusion plate, which will be illustrated hereinafter.

In the first embodiment of the present invention, as shown in FIG. 4 and FIG. 5, the metal extrusion plate 50 is disclosed. The metal extrusion plate 50 is manufactured in a manner of metallic extrusion to form an elongated plate extending along a first direction D1. Then, the metal extrusion plate 50 is further processed to form a plurality of flat plate sections 51 and connecting sections 53 which are interlaced and are still integrated. Each of the connecting sections 53 connects the two adjacent flat plate sections 51. Subsequently, the metal extrusion plate 50 is adequately bent at the connecting sections 53 so that the two adjacent flat plate sections 51 form a first included angle θ1 (as shown in FIG. 7). In the present embodiment as shown in FIG. 5, there are three flat plate sections 51 and two connecting sections 53 for illustration. However, in other embodiments, the metal extrusion plate 50 includes N flat plate sections 51 and N−1 connecting sections 53, wherein N is a positive integer greater than 1.

FIG. 6 further shows a partially enlarged view along the A-A′ cross-sectional line in FIG. 5. Before bending the connecting sections 53, each of the connecting sections 53 is formed with a groove 530 extending along a second direction D2 which is perpendicular to the first direction D1. Each of the grooves 530 forms a first incline 531 and a second incline 532 opposite to the first incline 531. The first incline 531 and the second incline 532 form a second included angle θ2 therebetween.

For the illustration, the connecting section 53 could be further defined with a first block 533, a second block 534, and a third block 535 which are integrally formed. A side of the first block 533 is connected to one of the two adjacent flat plate sections 51. A side of the second block 534 is connected to the other one of the two adjacent flat plate sections 51. Two opposite sides of the third block 535 are connected to the two adjacent flat plate sections 51 respectively. Thus, the first block 533, the second block 534, and the third block 535 collaboratively define the groove 530. The first incline 531 is located on the first block 533, and the second incline 532 is located on the second block 534. Furthermore, the flat plate section 51 has a first thickness T1, and the third block 535 has a second thickness T2, wherein the first thickness T1 is greater than the second thickness T2. That is to say, the groove 530 does not cut off the connecting section 53. The flat plate sections 51 and the connecting section 53 are maintained as being as a whole. The third block 535 should have a sufficient thickness so as to prevent any fraction occurs during or after bending.

As shown in FIG. 7, the aforesaid metal extrusion plate 50 is bent at the connecting section 53 so that the first incline 531 and the second incline 532 abut against each other (that is the first incline 531 and the second incline 532 attach to each other) so that the two adjacent flat plate sections 51 form the first included angle θ1 to form the supporting frame 5 of the display stand 2000. It is understandable that the first included angle θ1 is the supplementary angle of the second included angle θ2, and vice versa. In the present embodiment, the first included angle θ1 and the second included angle θ2 are both about 90 degrees.

Please refer to FIG. 5. Preferably, at the two ends of the metal extrusion plate 50, either of the flat plate section 51 is formed with a first engagement structures 58. The first engagement structures 58 could be easily formed as a notch or a protrusion by post-processing. Furthermore, the metal extrusion plate 50 comprises a first surface S1 and a second surface S2 opposite to the first surface S1. In this embodiment, the groove 530 is formed on the first surface S1; however, in other embodiments, the groove 530 could be formed on the second surface S2. Preferably, the material of the metal extrusion plate 50 is aluminum or aluminum alloy.

With reference to FIG. 2, FIG. 3, and FIG. 7, the second embodiment of the present invention discloses the supporting frame 5 of the display stand 2000. The metal extrusion plate 50 is bent to form the supporting frame 5 which is disposed on the base 3. Thus, the flat plate sections 51 and the connecting sections 53 encompass and form a receiving space 59. The elevating module 7 is disposed in the receiving space 59 so as to move up and down with respect to the supporting frame 5.

The supporting structure 8 is, but not limited, an iron frame disposed in the receiving space 59 and fastened to the supporting frame 5. In this embodiment, the supporting structure 8 abuts against all the flat plate sections 51 of the supporting frame 5 to enhance the overall strength. Practically, the objective of enhancing structural strength is achieved through that the supporting structure 8 abuts against at least two of the flat plate sections 51. The base 3 further has a second engagement structure 38 which could be, for example, protrusions or screws. The first engagement structures 58 of the supporting frame 5 are adapted to engage to the second engagement structure 38 so that the supporting frame 5 could be secured onto the base 3.

The elevating module 7 further comprises a slide element 71 and a holder 73 connected to the slide element 71. The slide element 71 slides along a slide 9 with respect to the supporting frame 5. The slide element 71 and the slide 9 are both disposed on the supporting structure 8, and the holder 73 is utilized to connect to a display (not shown).

The third embodiment of the present invention is shown in FIG. 8. The difference is that the grooves 530 could be optionally formed on the first surface S1 or the second surface S2 so that the supporting frame 5 may have more variations to meet the user's requirements. As shown in FIG. 8, a plurality of flat plate sections 51 and connecting sections 53 are integrally formed and bent as the supporting frame 5. Because a portion of the grooves 530 of the metal extrusion plate 50 are formed on the first surface S1 and others are formed on the second surface S2, the bending orientations could be changed. Moreover, the second included angle θ2 of the metal extrusion plate 50 could also be varied according to the requirements. The first included angles θ1 shown in FIG. 8 include right angles with 90 degrees, and obtuse angles larger than 90 degrees. For example, if one of the first included angles θ1 is required in 120 degrees, the second included angle θ2 at the groove 530 is designed as 60 degrees before bending.

It could be understood that the metallic extrusion processes for manufacturing the metal extrusion plate 50 merely need small molds. Actually, the molds merely need to meet the requirements of the cross-section of the metal extrusion plate 50. The subsequent manufacture processes of grooving and bending are both simple so that the costs of manufacture can be reduced as well as a slim stand can be obtained.
